Coolescence LLC

Coolescence LLCwas a privately funded research company located in Boulder, Colorado. The company was originally formed to rigorously examine repeated experimental reports of so-called 'cold fusion' (low energy nuclear reaction - LENR), generally manifesting themselves in the form of unexpected or ‘excess’ heat, from a number of scientists around the world. Over the past 12 years the Coolescence team has replicated the most celebrated of these experiments, with no positive results that have not been attributable to measurement artifacts or chemical effects.

While researching cold fusion, Coolescence actively collaborated with a number of university and national laboratories, including the U.S. Naval Research Laboratory, the University of Missouri, the University of Colorado, and the Italian ENEA laboratory.

As an outgrowth of these efforts we spent several years researching the effects of surface modification and doping on hydrogen gas insertion into palladium. We have presented and published our mainstream experimental and theoretical work in major journals, contributing to the field of Hydrogen Energy Science.​​The consistent results obtained in our lab, together with analysis of numerous historical data sets from other researchers led us to conclude that it is unlikely there is an excess heat effect. In addition, after significant exploratory work, we concluded that commercial application of our work on surface modification was unlikely to be fruitful in the near term. We filed for a patent on the surface modification work, but concluded that commercial viability was far enough in the future that it made sense to end operations at Coolescence and shut down. The laboratory in Boulder was closed at the end of October 2017.

In hopes that others may learn from our experiences we have created this website as a repository for the experimental work that was done. Explore the website to find out more about our replication work, our publications, and members of the Coolescence team. An archive of all on-line lab books, datasets, images and reports generated in Coolescence’s 12 year effort has been preserved here.
